Wood Sorrel

Oxalis stricta · also: oxalis, sourgrass, oxalide

ripe now 🗓 Spring through fall

How to ID it

Looks like clover but leaflets are heart-shaped (clover's are oval/rounded with a pale crescent).
Three leaflets that fold down along their midrib in evening / bright sun.
Small 5-petalled yellow flowers; tiny okra-like upright seed pods.
Tastes bright and lemony — the giveaway.

⚠ Safety & lookalikes

Safe as a trailside nibble. Contains oxalic acid (the tang), so it's a garnish/snack, not a bulk green — don't eat bowlfuls.

The little lemony clover-lookalike growing in lawns, cracks, and garden edges. A fun, safe, instantly-rewarding nibble — the bright sour hit makes it a favourite for kids and a nice trail snack.

Harvest

Pinch leaves, flowers, and young seed pods — all edible and all tangy.
Grows everywhere; take a little as you pass.

Prep

Eat raw as a trail nibble, scatter over salads, or use as a lemony garnish on fish and soups.
Steep a handful in cold water for a lightly sour “lemonade.”

Notes

(Nothing to log really — it’s everywhere. A good confidence plant.)
